There's a ton of discussion on this. But I really want to know how your pressures work out.
This might be a little simplistic... but consider that the tire engineers optimized the compound, construction, and tread profile for a certain size/area contact patch... since the area of the contact patch is a function of weight divided by tire pressure, it makes sense that lighter cars should run proportionally lower tire pressures to get the same contact patch area.So the higher recommended pressures are based on 3000lb+ cars?
I've sat in an HPDE class where it was recommended to raise pressures above street. Seemed curious to me as track use was going to heat them up and raise pressure even more. Is there a rational for this, on any weight car?
